Fume Hood Specific Sash Setup and Calibration
This section presents the steps for calibrating the FHC sash sensors for Application
2941 and Application 2942.
Single Vertical Sash (Setup and Calibration)
This section includes steps for setting up and calibrating a single vertical sash fume
hood.
1.
Set REPORT to
SINGLE VERT
.
2.
Measure the width of the sash opening in inches (cm). Set VERT WIDTH1 to
this value.
3.
Measure the height of the vertical sash in inches (cm). Set VSASH HGHT1 to
this value.
4.
Measure the distance that the vertical sash can travel in its track in inches
(cm). This value does not have to be equal to VSASH HGHT1. Set TRACK
HEIGHT to this value.
Vertical Sash Fume Hood with Bypass Area Open and Closed.
5.
Open the sash until its top edge covers the bypass opening. Measure the
height of the sash opening in inches (cm). Set BYPASS HGHT to this value.
NOTE:
The bypass area of the fume hood is an opening that increases when
the sash closes and decreases when the sash opens.
6.
Skip Step 6 unless there is a special requirement on the job, the default will be
used.
If the bypass area has an airflow restrictor covering and flush with the open
area, such as a perforated grille or louvers, estimate the percentage of the
bypass area that is open. Set BYPASS OPEN to this value. If there is no
restrictor, set BYPASS OPEN to 100, this value applies to the majority of fume
hoods
7.
Measure the fixed area of the fume hood in square feet (m2). Any fume hood
leakage must be accounted for in this measurement. Set FIXED AREA to this
value.
